Abstract

Background: A concern for breeders is whether an animal ranking based on genetic evaluations is similar to that obtained from show-ring judging. Objective: to determine the association between rankings for Braunvieh (BR) and Brown Swiss (BS) cattle of Mexico based on show-ring judging and their...

Abstract

Agribusinesses of dairy cattle in the country are quite heterogeneous, which is why it is necessary to classify them for their analysis and adequate improvement. The objective of this study was to stratify family dairy producers in the Jalisco Highlands that used technological development advice...

AbstractFull Text

Selection indexes were developed for productive and reproductive characteristics of Braunvieh cattle in Mexico, through the desired gain procedure. The data for this study were obtained from the Mexican Braunvieh Cattle Association. Records from 21,547 animals born in 86 herds, offspring of 632...

Abstract

Heritable abnormalities can cause a reduction in productive performance, structural defects, or death of the animal. There are reports of hereditary abnormalities in Braunvieh cattle from several countries, but no evidence was found on their existence in Mexico. In this study, 28 genes associated...

Abstract

The objectives were to estimate variance components, and direct (h2) and maternal (m2) heritability in the growth of Tropicarne cattle based on a random regression model using B-Splines for random effects modeling. Information from 12 890 monthly weightings of 1787 calves, from birth to 24 months...

Abstract

The reproduction of dairy cows can be affected by factors related to management. The objective of the study was to evaluate the reproductive behavior of dairy cows in agribusinesses with two technological levels (TL): transition and entrepreneurial, which use CHAPINGO-AGROPEC Star® advice and...

Abstract

The objective of this study was to determine the magnitude of genotype by climate interaction (GCI) in the national genetic evaluation for weaning (WW) and yearling (YW) weights of Mexican Braunvieh cattle. The numbers of performance records and animals in the pedigree were 12,364 and 25,173 for...

Abstract

In México, there are no studies whose purpose has been characterizing the production units with registered cattle herds. These studies are important because they allow designing successful genetic improvement programs and the transfer of their results to commercial producers. The objective of this...
